       long drawn out discussion of the  program.   it's  a  good
       idea  to  break  this  up  into  subsections using the .SS
       macros, like these:

       Let's   'dark.fits'   is  darkfame,  and  'sun1.fits'  and
       'sun2.fits' are scientific exposures. The  darkframe  sub-
       tracting   is   done   by   ls   sun?.fits   |  darkbat  @
       dark=dark.fits

       _/_u_s_r_/_m_a_n_/_m_a_n_*_/_*_._* unformatted (nroff source) man pages

       other man pages to check out, like man(1),  man(7),  make-
       whatis(8), catman(8) munipack(1), ftsbat(1), meandark(1)

       The  image values are represented by the real type REAL*4,
       Using images with any extensive data types is  not  recom-
       mended.   Number of '?' characters in 'mask' is restricted
       to 10 (internal variable is INTEGER*4).
